Abstract
The utility model relates to a small crawler tractor, which belongs to an agricultural machine. The walking part of existing four-wheel tractors is rubber type and is easy for sinking and slipping when tilling in paddy field and muddy ground, and the existing hand-hold tractor can not reach the requirements of deep tillage when tilling in upland field. On the basis of a four-wheel tractor, the utility model is added with a set of crawler walking device, the walking device is composed of sealed metal chain crawlers surrounding on a guiding wheel and a driving wheel, and the crawler can be engaged with gear teeth of the driving wheel so as to accomplish walking motion. Therefore, the utility model is suitable for deep tillage operation in paddy field, muddy field and upland field.
Description
The utility model belongs to field machine, is by the improved a kind of baby track-layer of rubber tire four-wheeled tractor.
The crawler body of existing four-wheeled tractor is a rubber wheel type, though maneuvering performance is good, relatively adapts to current agricultural production, but because tire-contact area is little, in the paddy field with flush go up farming and easily sink and skid, the covering performance of digging when the dry land farming is bad, can not reach the requirement of ploughing deeply.
The purpose of this utility model is: on the basis of existing small-sized rubber tire four-wheeled tractor, increase by a cover track unit and an operating control, replace original rubber tire, become a tractor serves several purposes, because crawler belt and contact area of ground are big, overcome weak point of the prior art, solved sagging the skidding on ground, paddy field, be suitable for to dry land the deep ploughing operation, when carrying out project assignment such as farmland intertillage operation and transportation at needs, track unit can be laid down, the rubber tire running gear is installed, use original rubber tire operating control.
The purpose of this utility model realizes in the following manner: a kind of baby track-layer, be to increase by the rubber tire four-wheeled tractor cover track unit is installed, it is characterized in that guide wheel 1 is installed on the four-wheeled tractor guiding wheel shaft 2, drive wheel 14 is installed on the live axle semiaxis 2 13 of four-wheeled tractor, the even branch gear teeth 11 on drive wheel 14 excircles, osed top metallic bond crawler belt 9 is centered around on guide wheel 1, the drive wheel 14, crawler belt 9 and the gear teeth 11 interlocks.
Baby track-layer, it is characterized in that four-wheeled tractor integral type propons is separated in being adapted as, with turning pipe spreader 29 two open circuited axles 28 that turn are connected, the restriction screw 34 make turn the axle 28 during turning pipe spreader 29 can front and back freely swing, axle 28 is turned in stop screw 35 restrictions, and laterally string is moving in turning pipe spreader 29, to adapt to the buffer action of tightening device to guide wheel 1 and crawler belt 9.
Baby track-layer, it is characterized in that the bogie axle 7 in body middle part and frame fixed installation, on bogie axle 7, use bearing fixing bogie 10, the weight of bogie 10 and guide wheel 1 and drive wheel 14 together support trac.s, and guarantee the trac. orbital motion.
Baby track-layer, tightening device fixed support 33 on it is characterized in that tightening device front arm 3 usefulness connecting link pins 27 and guiding wheel shaft 2 is connected, the front end of tightening device recoil spring axle 5 is weldingly fixed on the tightening device front arm 3, tightening device recoil spring 4 is sleeved on the tightening device recoil spring axle 5, insert in the hole of tightening device back arm 6 rear end of tightening device recoil spring axle 5, tightening device back arm 6 is fixed by bolts on the bogie axle 7, and the degree of tension of trac. crawler belt is mediated by spring 4.
Baby track-layer, it is characterized in that installing on rear-axle differential 23 1 side shaft journals of four-wheeled tractor differential locking-device 25, fixed installation differential locking-device steering unit 24 on the differential locking-device 25, differential locking-device pin 26 is arranged on the differential locking-device 25, when four-wheeled tractor is installed track unit, by differential locking-device steering unit 24, differential locking-device pin on the differential locking-device 25 26 is inserted in the differential side gear hole, about two semiaxis be connected into a rigid shaft, diff does not play differential action, make two drive wheels with identical speed rotation, the trac. of this moment is a straight-line travelling.
Baby track-layer, it is characterized in that two semiaxis of four-wheeled tractor are divided into semiaxis 1 and 2 13 liang of joints of semiaxis respectively, in the middle of semiaxis 1 and semiaxis 2 13, castellated steering clutch 17 is installed, power-transfer clutch 17 is by fixed jaw 18, movable claw 19, pull back spring 21 constitutes, fixed jaw 18 is made into one with semiaxis 2 13, movable claw 19 is sleeved on the keyway of semiaxis 1 and semiaxis 2 13 junctions and can slidably reciprocates, the steering unit of steering clutch is by left steering control operating rod 15, right steering control operating rod 16 is respectively by turning to push rod 8, spindle arm 31, turn to shift fork 30 to control separating or combination of movable claw 19 and fixed jaw 18, as draw left steering joystick 15, make left side movable claw 19 separate left side fixed jaw 18, cut off left side drive wheel power, left track 9 slows down, make the track type tractor left-handed turning to.
The utility model compared with prior art has following advantage: because crawler belt and contact area of ground are big, is difficult for sinking and skidding, is suitable for operation on ground, paddy field, humidity, the pory field, and the deep ploughing that is suitable for turning up the soil.This machine and rubber-tyred tractor dual-use, dismounting, easy for installation, simple to operate, the comprehensive application performance is good.
